COMPRESSED-AIR WATER-ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 404,330, dated May 28, 1889.

Application filed February 28, 1389. Serial No. 301,524. (No model.)

To all whom it may concern:

Be 1t known that I, MICHAEL \VETZEL, a

, citizen of the United States of America, residing at Sidney, in the county of Cheyenne and State of Nebraska, have invented certain new and useful Improvements. in Compressed- Air \Vater-Elevators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawing, and to letters or figures of reference marked thereon, which forms a part of this specification.

My invention relates to certain new and useful improvements in that class of inventions known as compressed-air water-elevators.

The object of my invention is to provide a means whereby Water from a well or cistern or other body of water can be raised so as to give a constant flow without the immediate application of manual power; and my invention consists in the combination of an aircompressor, means for actuating the compressor, and in the construction of the parts, as will be hereinafter fully set forth, and pointed out in the claims. I

Heretofore it has been proposed to elevate water from wells or cisterns by means of compressed air which was forced into an airtight receptacle having a valve located at the bottom of the cistern in which the water was admitted, so that the water would be raised when air was forced into the hereinbeforementioned receptacle, which air-compressor can be operated manually when it is desired to raise the water. It will therefore be understood that I am not claiming, broadly, the

means for elevating water or liquids by com-.

pressed air.

In the accompanying drawing I have illustrated my invention by a sectional view, which fully shows one form of my apparatus, and in which A refers to a reservoir submerged in the water, this reservoir being suitably supported from above and provided with a valve, (0, which moves upwardly oif its seat. This reservoir A is connected by means of a pipe, B, with a flared ring, 0, the upper edge of which is connected to the lower end of a cylinder, O, by bolts or other usual means. Between the mceting edges of this ring 0 and cylinder 0 is tightly clamped the lower end of a cylindrical bellows, D, the upper end of which is secured to a circular plate, E, which is centrally provided with an opening, 6, the lower portion of said opening being formed into a valve-seat for a valve, F, which has an upwardly-projecting valve-stem, F, which passes through a tube, G, the upper portion of this valve-stem being connected to a pivoted arm, H, carrying a weight, w. The upper end of the tube G has secured thereto in any suitable manner a pulley, 7;.

K refers to a suitable frame attached to the cylinder 0, and to this frame, which may be composed of light rods, is an upper frame, K, which forms a support for a pulley or block, 75. The lower frame, K, carries outwardlyprojecting arms, to which is attached a windlass over which the rope L passes, this rope passing around the pulley 'i and block it to said Windlass.

IVithin the compartment A is secured a tube, M, the lower portion of which is conical, the upper portion having a seat for a ballvalve and suitable connections which communicate with the discharge-pipe N, which discharge-pipe is provided with a stop-cock. This discharge-pipe N may also communicate with distributing-pipes.

Upon the plate E is placed a heavy weight, IV, which will tend to compress the bellows.

The operation of my invention is as follows: When the bellows are compressed, the weight attached to the pivoted arm H, contacting with the frame, will move the valve F off its seat to establish free communication between the interior of the bellows and the outer air, and admit of the escape of confined air within the pipe B and reservoir A, thus permitting water to flow freely from the cistern into the reservoir A until a common level is attained. By turning the Windlass and drawing upon the cord the bellows are expanded and the valve moved off its seat to permit the ingress of air through the tube or pipe G. WVhen the bellows have been expanded to their full extent, the windlass is allowed to turn back and the valve is closed by the weight and pressure of the air. Now, as the bellows is compressed by the weight XV, air-pressure is createdin the receptacle A, which bearing upon the surface of the water will raise the water in the pipe M, so that it will be forced through the dis charge-pipes when the valves attached th creto are opened, and this fiowof water will continue until the bellows are fully compressed.

It will be observed that by relieving the pressure when elevating the water will flow into the receptacle A through the valved openings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as described, of the submerged reservoir provided at bottom with an inwardly-opening valve, a weighted bellows communicating through a pipe, 3, with the upper end of said reservoir, a valved water-discharge pipe leading from near the bottom of the reservoir, an air-tube entering the bellows, a valve and its stem, and a weighted lever for controlling the position of the valve.

2. The combination, in a eomprcssed-air water-elevator for wells, cisterns, or other bodies of water, of a frame or superstructure having a windlass attached thereto, a pulley, the cylindrical bellows provided with a weight and a valve-opening, said bellows being con nected by a pipe to a submerged reservoir having a valve, a, a discharge-pipe located within said rezeptacle, a valve to close the opening in the bellows, and a weighted lever to control the position of this valve, the parts being organized substantially as shown, and for the purpose set forth.

I11 testimony whereof I affix my signaturein presence of two witnesses.
